ABSTRACT:
A light emitting assembly (50) includes a metal circuit board (54) having a first surface and an opposite second surface, a light emitting module (52) mounted on the first surface of the metal circuit board, and a cooling module (58) attached to the second surface of the metal circuit board. A backlight device (90) includes a reflection plate (91), a diffuser sheet (93) disposed on the reflection plate and a plurality of light emitting assemblies (92) regularly arranged between the reflection plate and the diffuser sheet. Each light emitting assembly includes a metal circuit board (922) having a first surface and an opposite surface, a light emitting module (921) mounted on the first surface of the metal circuit board and a cooling module (923) attached to the second surface of the metal circuit board. The present light emitting assembly and backlight device can increase heat abstraction efficiency.
